According to China Central Television, Li offered to pay them for sex if they went home with him, but then proceeded to kidnap and imprison them.
[33][13][34][35][36][15] In July and August 2010, Zhang Xuanxuan attacked Li from behind, taking advantage of his unprepared digging of the tunnel.
[14][37] In May 2011, Cai Moumou was found to have gynecological disease and was unable to perform the obscene pornography Li Hao forced his captives to do.
In order to cover up the crime, Li and Duan laid Cai's corpse in a concrete pool in a hole.
[38] Li purchased a computer and video head, opening a broadband connection to his dungeon.
Li forced Duan, Jiang, Ma, Zhang Moumou and others to do obscene performances in his dungeon.
By the time of the incident, Li produced more than 50 obscene videos and collected thousands of yuan from viewing from Alipay and other forms of online banking.
On the evening of September 2, 2011, Li forced Duan, Ma, and Zhang Moumou to go to the same place for prostitution.
With the cooperation of Ma, the public security personnel rescued Jiang Moumou, who was detained in Li's dungeon.
Public security later rescued Duan and Zhang Moumou from the hotel and welfare lottery shop.
In September 2011,[40] a 23-year-old woman (Ma Moumou) escaped from his dungeon and reported Li to the police, leading them to his basement.
[40] A reporter named Ji Xuguang from Guangzhou was one of the first people to expose the case to the media.
[1][20][47][48][49] The two women who were murdered, Cai and Zhang Xuanxuan, had been dead for months by the time police had found their corpses.
[2] Duan, Jiang, and Zhang Moumou were charged with murder, but were given lighter punishments (shown leniency)[14] due to the situation Li forced them into.
[33][4] The six KTV women had worked at nightclubs, hair salons, karaoke bars, and a massage shop.
[8][17] In 2011, Guo Congbin said that the delay between when Li abducted the women and when he was finally caught and arrested was too long and indicated that the local police were ineffective.
Guo said that four police officers were suspended and that entertainment areas such as nightclubs and bars were to be more thoroughly inspected.
Reporter Ji Xuguang, from the Southern Metropolis Daily, was one of the journalists who exposed Li's crimes.
[7] At the time local authorities were shocked, and very few high level officials knew of the case.
[19] Resident Kou Yongxue, who lived in the building above the dungeon, said that Li's crimes were unimaginable and that they were still 'shuddering' at the sex slave case.
[8] The sex slave case is described in detail in a book written by Liu Baiju (刘白驹) titled "Sexual Offenders: Psychopathology and Control" (性犯罪:精神病理与控制).
